Title: Troubleshooting Guide: How to Fix Easy Anti-Cheat Errors and Application Issues


Gaming enthusiasts often encounter frustrating errors while trying to play their favorite titles. One common set of errors includes Easy Anti-Cheat (EAC) errors, application errors, and security violation errors that can prevent a game from launching or running smoothly. This troubleshooting guide aims to provide a comprehensive set of steps to help gamers overcome these issues and get back to enjoying their gaming experience.

Step 1. Restart and Update

  • The first step in resolving any gaming issue is to restart both Steam and your computer. Ensure that Steam and the game are up-to-date by allowing any pending updates to complete.

Step 2. Compatibility Mode

  • If restarting doesn't work, try running the game in compatibility mode. Right-click on the game executable, navigate to Properties, and under the Compatibility tab, select Windows 8 or 7 compatibility mode. Apply the settings and attempt to launch the game.

Step 3. Disabling Hyper-Threading or SMT

  • Some players have reported success by disabling hyper-threading (for Intel users) or simultaneous multithreading (SMT for AMD users) in the system BIOS. However, remember to re-enable this feature after playing the game.

Step 4. Allow Game Through Antivirus

  • Ensure that your antivirus program or Windows Security isn't blocking the game. Add the game executable to your antivirus' allowed apps list and check Windows Defender Firewall settings.

Step 5. Graphics Settings Adjustment

  • Lower graphics settings, switch to windowed or borderless mode, and reduce resolution and frame rate to minimize potential conflicts causing the errors.

Step 6. Disable G-Sync and Overlays

  • If you have Nvidia G-Sync enabled, try disabling it. Turn off overlays in applications like Discord, GeForce Experience, and Steam to rule out conflicts with the game.

Step 7. Clean Graphics Driver Installation

  • Perform a clean installation of your graphics driver to eliminate any driver-related issues. Download the latest driver from the manufacturer's website, and during installation, choose the option for a clean install.

Step 8. Update Windows and Install Visual C++ Redistributables

  • Keep your Windows system up to date by installing the latest updates. Additionally, download and install the necessary Visual C++ Redistributable packages provided by Microsoft to ensure proper runtime libraries.

Step 9. Uninstall and Reinstall the Game

  • As a last resort, uninstall the game, delete its installation folder, and reinstall it on a different drive if available. This can help eliminate any corrupted game files causing the issues.

Step 10. Seek Help from the Community

  • If the issue persists, it might be helpful to visit the game's official forums or community spaces. Other players might have encountered similar problems and could provide valuable insights or solutions.


Encountering Easy Anti-Cheat errors, application issues, or security violation errors can be frustrating, but with a systematic approach to troubleshooting, most of these issues can be resolved. By following the steps outlined in this guide, gamers can get back to their favorite titles and enjoy a smoother gaming experience. Remember that every system configuration is unique, so it's essential to try various solutions and see which one works best for your setup.
